1.5 Orientation of the Appliance
The front
The "front" refers to the side where the total locks at the swivel casters are located. With ERGO appliances,
a push handle is located at the front.
The rear
The "rear" refers to the opposite side to the front.
The right
The "right" refers to the right hand side when viewed from the front side (front).
The left
The "left" refers to the left hand side when viewed from the front.

Definition
A validated process to produce devices free from viable micro-organisms.
Sterilisation, sterilising and sanitation denote processes used to free materials and
objects from living micro-organisms including those in their dormant state (for example,
spores). The condition that the material and objects are said to achieve through these
processes is called sterile.
Generally speaking, steam sterilisation processes (autoclave) are utilised.
Used to clean small, complex and intricately structured components.
This cleaning principle is based on cavitation. Soft cavitation is not desired in ultrasonic
cleaning processes; consequently, the solution is often degassed in the ultrasonic
cleaning system using a special, integrated degassing programme before the cleaning
process.
The ultrasonic field in the liquid solution generates high and low pressure shock waves.
When such a low-pressure wave meets an object, hollow spaces filled with vapour are
induced at small air bubbles adhering to the surfaces of an object as contaminants.
When high pressure waves meet the cavity, compression causes the static pressure in
the cavity to rise until it surpasses the saturated vapour pressure. The vapour bubbles
condense abruptly at the speed of sound. This process sees peak pressures up to as
much as 1,450,380 psi (100,000 bar). This cyclic formation and collapse of hollow
spaces acts on and cleans the surface. As a result, dirt and other contaminants adher-
ing to the surface are removed mechanically.
An instructed person is a person who has been instructed on the possible risks result-
ing from improper behaviour when carrying out an assigned task and regarding the
necessary protective equipment and protective measures, and who has been trained
for this task, if necessary.
